The SWR spectra of an FeNi multilayer have been studied experimentally and theoretically. Non-propagating surface spin wave modes as well as standing volume modes could be observed. Values of the surface anisotropy, the spin wave stiffness constant and the effective magnetisation have been deduced from the spectra. The results obtained by SWR and torque measurements are discussed.
